Research On Traffic Accident Prevention Countermeasures Of Expressway

China's express ways are in a period of rapid devel opment.Due to the smooth passage of high ways,wide lane sand fully enclosed features,combined with various effective traffic safety facilities,it provides good driving conditions for the travel of vehicles and greatly improves the traffic in China.Transportation status.With the rapid devel opmen to fex press way construction,people's traffic travel efficiency has increased significantly.Undoubtedly,forthecountry,the high way is like the blood vessel sand meridians of the humanbody,laying asol idfoundation for the rapid devel opment of the national economy.However,with the continuouse xpansion of the scale of road construction,some security problems haveemerged.Especially the high incidence of traffic accident sisincalculable to the serious consequences of economic development,social stability and individual families.In recent years,with the rapid growth of high way traffic,traffic accident shave also increase dsign ificantly,causing serious damage to people's livesand property.Due to the late construction of the express way and the design of China's express way,the understanding of high way traffic safetyiss till relatively lacking.Coupled with objective reasons such as natural disasters and frequent accidents,China's express way shaveen tereda high-risk emergency period.In recent years,many majorroad traffic accident sand special incident shave occurred frequently,which has become one of the major public hazards that threaten public health.Therefore,this problem ha sgradually attracted wide attention fromall walks of life.Not only is the number of high way traffic accidents increasing,but the severity is also increasing.After the traffic accident,there sulting congestion durationis also prolonged,posing agreat threat to the public's life and property,and affecting people's normal travel.Compared with general road traffic accidents,high way traffic accidents have more casual ties and are more likely to inducesec on dary accidents.Although the seaccidents have the irnatural or artificial factors,there are still many problems in China's current risk control mechanism for highway traffic accidents.The current highway traffic accident riskmanagement level cannolongermeettheneeds of economic and social development and public transportation.Therefore,in-depth analysis of the causes of traffic accidents and coping strategies are of great significance for preventing traffic accidents and improving highway safety.This paper takes the two the or ies of accident causation system the oryandintrinsic safety theory as the starting point.Taking the express way in Xi'an asan example,this paper analyzes all aspects of highway trafficac acidents and how to avoid accidents.The measures to provide a feasiblere ference for the prevention of road traffic accidents on highways.
